靶點詳情

  • 最新研究進展：
    TNFRSF1B是一種細胞膜受體，屬于腫瘤壞死因子受體家族，它與腫瘤壞死因子（TNF）結合后，可以啟動多種信號通路，參與炎癥反應、免疫應答、細胞增殖和細胞凋亡等生物學過程。近年來的研究表明，TNFRSF1B在許多疾病中都扮演著重要的角色，例如自身免疫疾病、腫瘤和炎癥性疾病等。針對TNFRSF1B的抗體和抑制劑已被廣泛研究作為治療上述疾病的候選藥物。此外，對TNFRSF1B基因的突變和多態(tài)性研究也有助于進一步了解該受體在疾病發(fā)生和發(fā)展中的作用。
  • 功能：
    Receptor with high affinity for TNFSF2/TNF-alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin-alpha. The TRAF1/TRAF2 complex recruits the apoptotic suppressors BIRC2 and BIRC3 to TNFRSF1B/TNFR2. This receptor mediates most of the metabolic effects of TNF-alpha. Isoform 2 blocks TNF-alpha-induced apoptosis, which suggests that it regulates TNF-alpha function by antagonizing its biological activity.
